I just recieved an Olympus C-720 ultra zoom and am looking to add wide and tele conversion lenses to it. I have noticed that there are a bunch of different diameter lenses available and even more tube adapters to choose from. My Oly has the proprietary 45.6mm thread found on the Ultra Zooms. If I buy a lens, it will either have to be a larger diameter or smaller diameter, but not 45.6mm. Question: Is there any advantages/disadvantages to going to either a larger thread or a smaller thread? I've seen anything from a 58mm rear to a 37mm rear with adapters allegedly meant to fit my camera. Please help this rookie out!!! Thanks!
